    Hi Todd,

    Try going here:

    http://www.clockwk.com/lunars/

    for a first taste. This site is developed and
    maintained by Frank, a member of this list.

    Secondly there is a whole body of information on
    historical uses for lunars, much of it in the archives
    of this list here:

    http://www.offsoundings.info/navl.htm

    Much modern day use is from (temporarily) land locked
    modern celestial navigators who use the technique to
    practice their skills without real need for a horizon.
    It is highly demanding because, as you might notice
    from my recent data, a tiny error in measurement
    contributes a substantial change in predicted
    longitude.

    Regards

    Mike
